Definitions

  • the subject of the invention is a molecule characterised by the general structure as no. I., where the meaning of x is 1 or 2 valency metallic ion adequate from therapeutic point of view, the value of n is 1 or 2, or its metabolite which is used the for manufacture of a medicament for the treatment or prevention of embryonic retardation or discordance.
  • the active constituent is applied in several formulated forms, among which the most important products are oral products (tablet, capsule) and which are known by their widespread registered name as Doxium manufactured by e.g. the OB Lab. (Switzerland).
  • oral dosage of Doxium has a favourable effect on the pathological permeability of the capillaries, and the capillary resistance values.
  • the known indications for the oral application of the calcium dobesilate are the followings: microangiopathy; particularly retinopathy deabetica; chronic venous insufficiency; primer varicosity; pregnancy varicosity; leg ulcer; night sural spasm; ankle oedema.
  • microangiopathy particularly retinopathy deabetica
  • chronic venous insufficiency primer varicosity
  • pregnancy varicosity pregnancy varicosity
  • leg ulcer leg ulcer
  • night sural spasm ankle oedema.
  • it is applicable as an adjuvant in the following cases: external thrombophlebitis; postthrombotic syndrome; oedema; stasis dermatosis; piles complaint.
  • the calcium dobesilate effects via the regulation of the pathological capillaric wall functions (increased permeability and reduced resistancy). It inhibits the decomposition of the collagen fibres, reduces the hyperviscosity of both the plasma and the blood. Indirectly it inhibits the lymph flow, and as a consequence of this reduces the oedema.
  • Maximum blood concentration value can be reached 6 hours after the oral dosing of 500 mg calcium dobesilate, which is about as high as 8 ⁇ g/ml. Between 3 and 10 hours a platform can be experienced. After 24 hours dosing its blood concentration is 3 ⁇ g/ml. As an average the half-period of plasma is 5 hours.
  • Calcium dobesilate is connected to the plasma peptide by its 20-25% rate. It can not be transferred through the barrier between the brain and the blood and not even through the placenta barrier. It can be detected in small quantity in the mother's milk. In the first 24 hours about 50% of the orally dosed quantity is secreted with the urine, and very similar to this value is its secretion with the faeces. Major quantity of the compound is eliminated without its any transformation.
  • the compound Independently from the period of the treatment, the compound is well tolerable. Its toxicity is very low, the LD 50 value tested with mousses is 700 mg/kg. According to the literature data known up to the present there is not any medicine interaction.
  • the embryonic retardation During the pregnancy several clinical picture can be formed, one of them of which is the embryonic retardation. It means, that the development inside the uterus is retarded compering it to the average development ratio in given pregnancy phase. According to the domestic and international statistical data the frequency of the embryonic retardation is within 10-30%. Large fluctuation refers to the fact, that the demand for the detection and the instrumental conditions were established only in the past 5-10 years. Babies who are born with 2500 g birth weight nowadays belong not to the retarded new-born infant but to the premature birth, especially if the birth happened before the 37th pregnancy week.
  • Placenta also could be a possible source, e.g. disorders in the uterus development, insertion difficulties of the placenta, its early ageing, or the discordance twin pregnancy.
  • these factors have not been examined completely, since beside congenital uterus disorder and after retarded pregnancy even a normal pregnancy can be developed.
  • the subject of the invention is the use a molecule characterised by the general structure as no. I., where the meaning of x is 1 or 2 valency metallic ion adequate from therapeutic point of view, the value of n is 1 or 2, or the application of its metabolite for the manufacture of a medicament for the treatment or prevention of embryonic retardation and for the treatment or prevention of discordance.
  • the chemical structure of the molecule is presented in the 1st Figure.
  • the above active constituent is suitable for the treatment of the developed embryonic retardation in its early stage or the prevention of it. Predisposing factors were discussed previously, consequently in the case of their earlier accumulated occurrence the development of the illness is more probable. If in the foregoing pregnancies retardation happened only in one case, presuming the development of a further retardation is not correct. However after two or more retarded new-born infants, in the case of a further pregnancy in all probability the clinical picture will be developed again.
  • the blood supply of the placenta on the maternal and the embryonal border is increased, and consequently the oxygen and nutrient supply towards the embryonic side is intensified.
  • the blood congestion and the formation of the microthrombus comes to an end.
  • the maternal and embryonal blood vessels do not mix, by the improvement of the maternal blood volume and blood pressure the flow of blood volume and blood pressure towards the embryo is intensified too.
  • the dosing of the active constituent has a favourable effect on the development of the gemini-B or -C being retarded in the development before.
  • the positive result is due to the improvement of the oxygen and nutrient supply in the placenta, which provide the development of the gemini-B or -C.
  • the test of the calcium dobesilate was made with pregnants divided into three groups.
  • embryonal retardation was diagnosed by ultrasound analytical method according to the measurements mentioned before as diameter of the embryonic temporal bone, circumference of the embryonic skull, circumference of the embryonic chest, diameter of the embryonic chest, length of embryonic femur and by embryonal cardiovascular examinations, i.e.:
  • Initial dose was daily 3x2 Doxium tablets (250 mg calcium dobesilate per capsule).
  • the maintenance dose was daily 2x2 Doxium tablets.
  • the recommended minimal daily calcium dobesilicate dosis is 500 mg and the maximal is 3000 mg.
